The WIKA high-quality MA diaphragm pressure switch is developed for safety-critical applications. The high quality of the WIKA MA diaphragm pressure switch is following ISO 9001, which ensures reliable monitoring of your plant. In production, the switches are traced by quality assurance software at every step and subsequently are 100 % tested. All wetted materials are from stainless steel as a standard. To ensure as flexible operation as possible, the pressure switches are fitted with micro switches, which enable the switching of an electrical load of up to AC 250 V, 20 A directly. For lower switching power ratings, such as for PLC applications, argon gas-filled micro switches with gold-plated contacts can be selected as an option. For applications with special requirements on the wetted parts, versions with materials from PTFE, Monel or Hastelloy are available. By using a diaphragm measuring system, the model MA pressure switch is extremely robust and guarantees optimal operating characteristics. For setting ranges from 4 … 40 bar a piston replaces or completes the diaphragm as a measuring element. The wetted parts of this variant from stainless steel are particularly suited for liquid media.

The SIKA VTM 15 turbine flow sensor is made for flow measurement or dosing applications for liquids. Because of the very compact design, the extensive measuring range and the convincing precision of measurements, almost unlimited applications are possible. The sturdy bearing materials – sapphire and tungsten carbide – also guarantee an exceptionally long endurance. The liquid flowing into the SIKA VTM 15 turbine flow sensor is split into individual jets by the guiding blade. These jets hit the rotor evenly from different directions, setting the rotor in motion. The rotation speed of the rotor is then converted to an electrical pulse signal (frequency): The rotor is fitted with magnets and a Hall effect sensor detects the rotation of the rotor. A flow-proportional frequency signal (square-wave signal) is made available. The construction of the guiding blade and rotor enables to realize the very low start-up flow values.
